Abstract: On object of the present invention is an agent for the reduction of the degree of shrinkage in hydraulic binders, whereby said comprises an alkanolamine of formula R—NH—(AOH) wherein R is hydrogen or a linear or branched aliphatic or cyclic C1-C6-alkyl group, and A is a C2H4-group or C3H6-group, alone or in combination with hydroxy compounds and/or ethers. Furthermore a method for the reduction of the dry shrinkage of binders such as cement, admixed cement, puzzolanas and thereof produced mortars and concretes by means of such a shrinkage reducing agent is described.

Abstract: A morpholine group comprising catalyst of the general formula, ##STR1## wherein n+m is >1 and R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9, R.sub.10, R.sub.11, R.sub.12, R.sub.13 and R.sub.14 are independently from each other hydrogen or an alkyl group, particularly a methyl or an ethyl group, is described. Said catalyst is particularly suitable for the use in storage stable polyurethane (PU)-compositions usable as adhesives, sealings, coatings or pretreatments with a primer. Said PU compositions have a delayed skinning time and thus an extended assembly time but nevertheless a fast development of strength, and they are suitable for the application on metal, glass, ceramics, wood, cementitious substratums and plastic substratums.

Abstract: Disclosed is a glass body suitable for cementing to a further material. At the time of cementing, there is at least one profile of a cement on the glass body, and it is already solidified at the time of cementing and serves as a range spacer. Furthermore, there is a profile of a second cement on the glass body which cement is still moldable and has adhesive characteristics at the time of cementing. When producing the adhesive connection, the second cement is formed and pressed against the other material. Because the profile of the second, still adhesive cement is directly on the glass body or possibly a layer of a material impermeable to ultraviolet or, where necessary, an intermediate layer of primer, a very good adhesion can be achieved.
